In this paper, mechanical buckling analysis of composite annular sector plates with bean shape cut out is studied. Composite material sector plate made of Glass-Epoxy and Graphite-Epoxy with eight layers with same thickness but different fiber angles for each layer. Mechanical loading to form of uniform pressure loading in radial, environmental and biaxial directions is assumed. The method used...

A method of optimal material design is applied to the problem of controlling the distribution of the electric field within a material heated by microwaves in closed cavities. Analytical and computational procedures are presented for a layer in a single-mode rectangular waveguide applicator. These determine the optimal placing and micro-geometry of composite controlling materials. The particular...

After the fifties Until the beginning of the fifties his research work concentrated upon insulin and glucose, focusing, during the last two thirds of his scientific curriculum, on certain particular features of cellular biology. While studying the enzymatic aspect of carbohydrate metabolism, de Duve separated and analysed different cell components and discovered two new ones: the lysosomes in 1...

In the work we analyze three cases of unusual dyadic deaths when the perpetrator of homicide committed suicide shortly after the murder. In the first case a man stabbed his girlfriend with a knife and subsequently committed a car crash suicide. In the second case an apparent simultaneous hanging of a married couple turned out to be homicide-suicide act. In the last case a man shot his ex-wife w...

The article is concerned with a new nonlocal model based on Eringen’s nonlocal elasticity and generalized thermoelasticity. A study is made of the magneto-thermoelastic waves in an isotropic conducting thermoelastic finite rod subjected to moving heat sources permeated by a primary uniform magnetic field and rotating with a uniform angular velocity. The Laplace transform technique with respect ...
